June 11, 1946. w. D. ROSSITER SEALING MEANS FOR DOORS Filed Nov. 21,1944 TEE WZ'LLIAM EJ217551 Patented June 11, 1946 William D. Rossiter,Toledo, Ohio Application November 21, 1944, Serial No. 564,493

2 Claims.

This invention relates to means for preventing the doors of cabinetsfrom being opened without detection. It is particularly desirable foruse in connection with cabinets of the type used in buildings to housefire extinguishers in a manner to prevent saboteurs and others fromhaving access thereto, without detection, to remove the chemicalscontained therein or to substitute an inflammable liquid for the fireextinguishing chemicals.

The object of this invention is the provision of a, simple, efiicientand novel form of sealing the like, which is operable in connection witha swinging door-locking control to secure such control in lockedposition, and includes a fragile part that is breakable by an unlockingmovement of the control to indicate that the door has been opened.

The invention is fully described in the following specification, andthree embodiments thereof illustrated in the accompanying drawing, inwhich- Figure 1 is a perspective view of a cabinet equipped with oneform of locking device for the door and having the sealing feature ofthe present invention associated therewith; Fig. 2 is an enlargedhorizontal cross-section taken on the line 22 in Fig. 1, with partsbroken away; Fig. 3 is a fragmentary detail of a door locking means withthe fragile sealing part associated therewith; and Fig. 4 is an enlargedfront elevation of the In the drawing, the fastening means for the doorI, shown in the present instance in connection with a cabinet 2,includes a control handle or member 3 pivoted to the door adjacent tothe free edge thereof for swinging control movements in a plane parallelto the door face. This handle is carried at the outer side of the doorby a shaft 4 projecting through the door and provided at its inner endwith a cross-arm 5 having upper and lower locking rods or bolt members 6projecting in opposite directions from its opposite ends whereby theouter rod ends are moved into and out of respective upper and lowercasing sockets by turning movements of the handle, as well understood inthe art. In the present instance, when the rods 6 are in locked'positionthe handle is vertically disposed with an edge adjacent to the free edgeof the door.

For the purpose of the sealing feature of my invention, the handle 3 inits outer side or face,

preferably near its pivoted end, is provided with an outwardly openingrecess or cabinets 1 having a side edge thereof adjacent to the casing 8open, as shown at 9. The recess 1, in the present instance, is ofcircular form with its edge-opening occurring at one side of its center.At each end of theopening 9 is provided an overhanging lip or lug H].

A plate or disk ll of easily breakable fragile material, such forinstance as glass, is positioned an edge projecting through the edgeopenin 9 beyond the side edge of the handle and toward the free edge ofthe door. This member I l is easily insertable into the recess back ofthe lips ID, as indicated by dotted lines locking part l3 which mayconstitute the shackle of a pad-lock I4, and also has engagement withear I5 attached to and projecting outward from the casing 8. It isapparent that when a locking member is engaged with the fragil elementII and with the ear IS, the handle cannot be swung to the left or inclockwise direction, in the present instance, to release the bolt member6 from locking engagement with the easing without breaking the aperturededge of said which the member I3 is engaged, thus indicating that thecabinet has been opened. At the same time this sealing means for thedoor will not prevent an easy and rapid opening of the door should anemergency therefor arise. After such a breaking of the sealing element,a new element maybe substituted therefor, and thelock I 4 easily andquickly operated to lock it to the ear l5 and thus seal the door inclosed position the same as before.

I wish it understood that my invention is not limited to any specificconstruction, arrangement or form of the parts, as it is capable ofnumerous modifications and changes without departing from the spirit ofthe claims.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent, is:

1. A means for sealing a door in closed relation to its casing,including a door lock control member movable in a plane substantiallyparallel to the door to unlock th door, a sealing connection betweensaid member and the casing and including a fragile element replaceablycarried by said member and a lock connecting said element and the casingwhen the control member is in doorlocking position, said breakableelement being broken by movement of the control member from lookin toreleasing position.

2. A means for sealing a door in closed relation to its casing,including a door lock control member carried by the door and movable ina lane substantially parallel to the door to effect an unlockingthereof, said member having a rea door unlocking movement of the controlmem ber.
